Enable silent build rules by default. You can still use verbose build rules by using any of the following methods: * run `configure` with the `--disable-silent-rules` argument * run `make` with the `V=1` argument This hides the compiler command line which makes debugging users' problems more difficult. To compensate for that, this prints the build flags separately, but a lot less frequently: For each part of the build (`libgphoto2_port.la`, iolibs, `libgphoto2.la`, camlibs), if something of that part has been rebuilt, prints the build flags (_CPPFLAGS, _CFLAGS, _LIBADD, _LDFLAGS) once. Always prints the environment variables CPPFLAGS CFLAGS LDADD LIBADD LDFLAGS once, whether they are the defaults the configure script sets or given on the `make` command line. Not all make recipes have been converted to be completely silent, but the majority (especially the Automake standard recipes) are now silent.
Rules for the API docs:
1. DO NOT DOCUMENT ANYTHING YET
2. If you know a method to keep API docs and internal docs apart, with
doxygen, please tell us.
3. If this has been solved, start documenting the external interface.
Thank you.
